Technical Details

The packer is custom made and has been designed to protect packed files from being debugged, emulated, or unpacked. The code in the packer stub is difficult to read and analyze since it has been obfuscated quite well. There are many decryption loops for the packer code itself which it executes during runtime and the code seems to be polymorphic.The contents of the packed files are usually password stealers for onlinegames. They may also include some other types of malware such as trojans and worms.
